ConnectionRefusedError：[Errno 61]连接被拒绝＆无法连接到端点URL：http://127.0.0.1:3001

Question

I am trying to run integration tests using boto3 and aws. It seems the tests are unable to connect to the localhost endpoint so the tests are failing. I'm quite sure I've configured my aws environment variables correctly. I suspect that maybe there is no local server running but I'm still unsure how to fix the problem. Any help would be greatly appreciated.

I'm running on Mac Mojave, I've tried changing the ports that the server is attempting to connect to localhost:3000. I've also tried connecting to a server that I'm running using AWS Step Functions ( https://docs.aws.amazon.com/step-functions/latest/dg/sfn-local-config-options.html ) but with no luck.

Error messages from Log:

ConnectionRefusedError: [Errno 61] Connection refused

and

raise EndpointConnectionError(endpoint_url=request.url, error=e)
botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: "http://127.0.0.1:3001/2015-03-31/functions/AthenaDatabaseProvider/invocations"

Answer 1

Turns out I need to have the docker app running when I run tests. Hope this can help someone who might have run into the same problem!
